Chapter 1 introduced psychopathy and evaluated theories attempting to explain this disorder. Experiment 1 assessed passive avoidance learning in children with psychopathic tendencies. Results replicated previous findings with psychopathic adults indicating that this disorder is associated with poor passive avoidance learning. Experiment 2 developed a connectionist model of passive avoidance lea...

Introduction: Previous studies have shown that sesame oil affects memory and learning. In the present work, effect of a diet containing 10% sesame oil used during pregnancy was evaluated on short-term passive avoidance learning of offspring rats by Shuttle box. Methods: Female Wistar rats were divided into 2 groups (n = 9 each group). Control group consumed regular diet during pregnancy and...

The effects of a new TRH analog, TA-0910, orally administered, on experimental memory impairments for the one-trial passive avoidance response in anoxic mice (light-dark box), active avoidance response in basal forebrain (BF)-lesioned rats (shuttle box), and delayed alternation task in scopolamine-treated rats (T-maze) were studied. In mice, TA-0910 (3-30 mg) administered 60 min before the rete...

the aim of the present study was to investigate whether and by which mechanism; histamine can induce state-dependent retrieval of passive avoidance task. the pre-training or pre-test intracerebroventricular (i.c.v.) injection of histamine (20µg/mouse) impaired retrieval, when it was tested 24 h later. in the animals, which retrieval was impaired due to histamine pre-training administration, pre...
